Guides
Amorphicola
Amorphicola is a genus of jumping plant lice (psyllids) in the family Psyllidae, established by Heslop-Harrison in 1961. As psyllids, members of this genus are small, sap-feeding insects with characteristic jumping ability enabled by their enlarged hind femora. The genus belongs to the diverse psyllid radiation within the suborder Sternorrhyncha.
Aphalaridae
jumping plant lice, psyllids, lerp insects
Aphalaridae is a family of sap-sucking insects in the superfamily Psylloidea, commonly known as jumping plant lice or psyllids. The family contains approximately 749 species with worldwide distribution except Antarctica. Members are small, phloem-feeding insects, often highly host-specific. The family was revised in 2012 and 2021 to include seven subfamilies based on molecular and morphological data. Several species are significant agricultural and forestry pests, including the red gum lerp psyllid (Glycaspis brimblecombei) and the common pistachio psyllid (Agonoscena pistaciae).
Aphalarinae
Aphalarinae is a subfamily of true bugs in the family Aphalaridae, order Hemiptera. It comprises multiple tribes including Aphalarini, Caillardiini, Colposceniini, Gyropsyllini, and Xenaphalarini, with both extant and extinct genera. The subfamily contains at least 15 extant genera and several fossil taxa. Members are psyllids, a group of sap-feeding insects commonly known as jumping plant lice.
Bactericera
psyllid bugs, jumping plant lice
Bactericera is a genus of psyllid bugs (family Triozidae) established by Auguste Puton in 1876. The genus is predominantly distributed in the Palaearctic and Nearctic regions, with 24 recognized species in North America north of Mexico. Members are small phloem-feeding insects commonly known as "jumping plant lice." The genus includes economically significant agricultural pests, most notably Bactericera cockerelli (potato/tomato psyllid), which transmits the bacterial pathogen 'Candidatus Liberibacter solanacearum' causing zebra chip disease in potatoes.
Euphalerus
Euphalerus is a genus of jumping plant lice (psyllids) in the family Psyllidae, first described by Schwarz in 1904. Members of this genus are small sap-feeding insects that inhabit the New World tropics and subtropics. The genus is distinguished by specific wing venation patterns and genitalic structures characteristic of the Psyllidae family. Euphalerus species are associated with various host plants, though specific associations remain incompletely documented.
Freysuila
Freysuila is a genus of jumping plant lice (psyllids) in the family Psyllidae, established by Aleman in 1887. As members of the superfamily Psylloidea, these insects are small, plant-feeding hemipterans with characteristic jumping hind legs. The genus is poorly documented in scientific literature, with limited species-level information available. It belongs to a diverse group of phytophagous insects that specialize on vascular plants.
Liviidae
plant lice, psyllids, jumping plant-lice
Liviidae is a family of plant-parasitic hemipterans commonly known as plant lice or jumping plant-lice. The family comprises more than 20 genera and approximately 370 described species worldwide. Members are characterized by their ability to jump and their association with vascular plants as phloem-feeders. The family includes significant agricultural pests, most notably Diaphorina citri (Asian citrus psyllid), the primary vector of citrus greening disease (Huanglongbing). Liviidae was formerly treated as Triozidae, and recent taxonomic revisions recognize three monophyletic subfamilies: Euphyllurinae, Liviinae, and the monotypic Neophyllurinae.
Neotriozella
Neotriozella is a genus of psyllids (family Triozidae) established by Crawford in 1911. These small sap-feeding insects belong to the hemipteran superfamily Psylloidea, commonly known as jumping plant lice. Members of this genus are poorly documented in contemporary literature, with limited species-level information available. The genus is distinguished from related triozid genera primarily by genitalic and wing venation characters used in psyllid taxonomy.
Neotriozella hirsuta
Neotriozella hirsuta is a psyllid species in the family Triozidae, described by Tuthill in 1939. It belongs to a genus of jumping plant-lice that feed on vascular plants. The species epithet 'hirsuta' refers to hairy characteristics, though specific morphological details remain poorly documented in accessible literature. Like other Triozidae, it likely has a complex life cycle involving multiple nymphal stages and host plant specificity.
Pachypsylla celtidisumbilicus
Hackberry Disc Gall Psyllid
Pachypsylla celtidisumbilicus is a species of hackberry psyllid that produces distinctive disc-shaped galls on hackberry leaves (Celtis spp.). Adults emerge in fall and seek shelter to overwinter, often becoming household nuisances when they congregate on building exteriors. The species is one of at least seven Pachypsylla species associated with hackberry in North America, each producing a characteristic gall morphology.

jumping plant-lice
Phacopteronidae is a family of psyllids (jumping plant-lice) within the superfamily Psylloidea. The family contains at least 31 Afrotropical species, primarily in the genus Pseudophacopteron, with additional species in the genus Phacopteron reported from southern India. Most species are associated with host plants in the order Sapindales, particularly Burseraceae and Rutaceae. Some species are gall-inducers, while others are free-living phloem feeders. The family has been documented as containing pests of cultivated plants, including species damaging to Dacryodes edulis in Cameroon.
Psylla
jumping plant lice, psyllids
Psylla is the type genus of the family Psyllidae, comprising small sap-sucking insects commonly known as jumping plant lice or psyllids. The genus contains at least 110 described species, each typically associated with specific host plants. Psylla species are phloem-feeders that use piercing-sucking mouthparts to extract plant sap. While some species in related genera such as Cacopsylla are significant agricultural pests, Psylla itself includes species with more restricted host ranges, including Psylla alni on alders, Psylla betulae on birches, and Psylla buxi on boxwood. The genus is distinguished from similar taxa by morphological features and host associations.
Psyllinae
Psyllinae is a subfamily of plant-parasitic hemipterans within the family Psyllidae, comprising approximately 12 genera and at least 40 described species. Members are commonly known as psyllids or jumping plant lice. The subfamily includes economically significant pest species such as the apple psylla (Cacopsylla mali) and pear psylla (Cacopsylla pyri). Species exhibit biogeographic patterns correlating with altitude and regional flora, with Oriental elements dominating at lower elevations and Himalayan and Australian elements prevalent above 2500 m in montane systems.
Rhinocolinae
Rhinocolinae is a subfamily of jumping plant lice (psyllids) within the family Aphalaridae. The subfamily comprises approximately 15 genera, including both extant and one extinct genus (†Protoscena). These insects are small, phloem-feeding Hemiptera associated with host plants, though specific biological details for the subfamily as a whole remain poorly documented in available literature.
